To (ti/Z whom it may concern:

Be it known that I, CARL WALOHNER, a g, and a resident of Ermadingen, Switzerland, have invented certain new and useful Improvements in Windows, of which the following is a specification.

My invention relates to improvements in windows with sliding upper sashes and swinging lower sashes, whereby it is rendered possible to open the lower sashes at will either inwardly or outwardly for cleaning the window with perfect safety.

The objects of my improvement are, first, to provide a recess in the sill of the window frame; second, to provide a vertically movable supporting ledge, which has a tongue on its upper face and engages with its lower part in the recess of the frame sill; third, to provide means for raising and lowering the sup porting ledge; fourth, to provide the window frame on its internal faces at both sides and at the top with tongues; fifth, to provide the sliding upper sash with grooves on its external edge faces; sixth, to provide means for raising and lowering the uppersash seventh, to provide two lower sashes, which are normally guided by their grooves engaging the tongues of the frame and can be secured by the upper sliding sash and the supporting ledge on pressing the latter upward, while on lowering the latter the two lower sashes will be released and allowed to drop; eighth, to

provide external and internal windowhinges and to so arrange them, that when the window is completely closed and the lower sash is in its upper position only the upper internal hinges are operative and when the lower sash is in its lowest position the external hinges are operative while the members of the internal hinges are disconnected; and, ninth, to provide the supporting ledge with a dust and water guard. I attain these objects by the window illustrated in the accompanying drawing, in which Figure 1 is an internal view of the window in its closed state, Fig. 2 is an external view of the same in its closed state, Fig. 3 is a cross section through the same in its closed state on the line AA in Fig. 1, seen from left to right, Fig. 4 is a similar section, the lower sashes of the window being lowered and positioned to be opened inwardly; Fig. 5 is asimilarljsectionfthe lower sashes l being lowered and positioned to be swung outwardly Fig. 6 is an elevation of the lower internal left hinge, its loop being turned aside and the window being closed, Fig. 7 is a horizontal section through the line DD in Fig. 6, Fig. 8 is an elevation of the lower external right hinge, the lower sash being lowered and ready to be opened outwardly, Fig. 9 is a horizontal section through the line EE in Fig. 8, Fig. 10 is an internal view of a part of the frame sill, the board (1 being removed to show the device for raising and lowering the supporting ledge, and Fig. 11 is a cross section through the frame sill and the supporting ledge on the line FF in Fig. 10.

Similar letters of reference refer to similar parts throughout the several views.

The window frame d is secured in the wall opening in any known manner. Its sill is so cut out as to form a longitudinal recess (1 (see Figs. 3, 4 and 5), which in its middle is widened out downwardly so as to leave sufficient space for a metallic plate a and a cam f (see Figs. 10 and 11). A supporting ledge h is so shaped, that its lower part can engage in the recess (Z and a board (1 is fastened on the frame (1 for guiding the lower part of the supporting ledge h and for preventing it from shifting inwardly. The frame d is provided with tongues (Z on its internal faces at both sides and at the top. The two ends of the supporting ledge h are provided with grooves, in which the tongues d of the frame at engage, so that the ledge h is guided not only in the recess (1 but also bythe tongues if. The supporting ledge h is provided on its upper face with a tongue 7L1 in correspondence with the tongues d and moreover on its external side it is provided with a metallic dust and water guard m. This guard m is made sufficiently wide to overlap the sill even in the uppermost position of the supporting ledge h, see Fig. 3. The cam f already mentioned above is fastened on a square part of a pin e (Fig. 11), which latter is mounted to turn in the metallic plate a and in a suitable bush in the board (1 and carries on the internal end a hand crank g. 1

In Figs. 10 and 11 the cam f occupies its lowermost position (see also Figs. 4 and 5), so that the supporting ledge his lowered and rests on the frame sill and the board (1 The upper sash 'L is provided on its external edge faces with grooves '5 in which the tongues d d of the frame (1 engage, partly for vertically guiding the sash 'i and partly for tightening the top joint, in case the sash "L is pressed upward. The upper sash i is arranged to be raised and lowered in any known manner, for example by means of a cord Zr: led over suitable rollers and secured by a hook (Figs. 3, 4 and 5).

The two lower sashes c c are provided at the sides with grooves c 0 (Figs. 7 and 9) for the tongues d d of the frame (1, at the bottom edge with grooves 0 (Figs. 3, 4 and 5) for the tongue h of the ledge 7L and at the top edges with tongues 0 which can engage in the lower groove i of the upper sash i. It

will be evident, that, when the lower sashes c 0 rest on the supporting ledge 7L and the upper sashi on them, they can be safely guided by the lateral tongues d d of the frame (I and they will be secured on being pressed upward by the cam For this reason the two lower sashes may be left without any fastening or locking device.

As already indicated above, the window is provided with external and internal hinges, which are constructed in the following manner: The pivots of the two upper internal hinges a a are fastened on the frame d (Fig. 1) and those of the two upper external hinges I) b on the sashes c c (Fig. 2). The former are made longer than the latter for a purpose, which will be presently explained. These hinges a a and b b are so disposed on the window, that the pivots of the internal hinges a a completely engage in their loops (see Fig. 1), when the supporting ledge h is raised and the window thereby closed, while the pivots of the external hinges are at a certain height above their loops (see Fig. 2). The pivots of the two lower internal hinges a a are fastened on the sashes c c and their loops are hinged to the frame d, so that they may be turned aside (Figs. 1, 5, 6 and 7). These lower internal hinges are so disposed, that, when the window is closed, their pivots are just above their loops and permit the latter to be turned in and out (Fig. 1). The pivots of the two upper internal hinges a a are made so long, that they still remain in engagement with their loops on the supporting ledge 7L be ing lowered, provided, that the pivots of the two lower internal hinges a a engage in their loops and the latter support the two lower sashes c c. If, however, the loops of the two lower internal hinges a a are turned aside (Figs. 6 and 7) and the supporting ledge h is lowered byineans of the hand crank g and the cam f, the two sashes c a resting on the supporting ledge it will be further lowered, so that the pivots of the two upper internal hinges a a withdraw from their loops. The pivots of the two upper external hinges I) b are made so short, that they remain just above their loops, in case the loops of the two lower internal hinges a a have been turned and support the two sashes c c, after the supporting ledge h has been lowered. Only, when the loops of the two internal hinges a a are turned aside (Figs. 6 and 7) and the supporting ledge h is lowered, will the pivots of the two upper external hinges b b engage in their loops.

The pivots of the two lower external hinges b are fastened on the two lower sashes c c and so disposed, that they can engage in their loops at the same time as the pivots of the upper external hinges engage in their loops. The loops of the two lower hinges b b are provided with shells 1) 6 which may be soldered or otherwise fastened on them and leave each a recess, in which a lock Z fastened on the sash c (Fig. 11) can engage. The two locks Z Z are so disposed, that they engage in the said recesses between the shells b and the sashes c c, as long as the window is closed or the two lower sashes c c are supported by the turned-on loops of the two lower internal hinges a a However, when these loops are turned aside and the two sashes c c are so much lowered, that the pivots of the two lower external hinges b b engage in their loops, then the locks Z Z will be clear from the shells b 6 see Fig. 8, and be ready to engage beneath the shells b The window is operated as follows: Normally the window is closed, so that the supporting ledge h occupies its uppermost position and presses the two lower sashes c 0 against the upper sash i and the latter against the top of the frame d. Then the tongues d d 72/ c of the frame (I, the supporting ledge h and the two lower sashes c a respectively, which engage in the respective grooves, will prevent the three sashes "L and c c from moving. When it is desired to open the window outwardly as usual, the loops of the two lower internal hinges a a are left in position out of alinement with their pivots (Figs. 6 and 7) and the hand crank g is turned to lower the supporting ledge h. Thereby the twolower sashes c c are also lowered until the pivots of all the external hinges b b and b b engage in their loops, while the pivots of the two upper internal hinges a a withdraw from their loops and those of the two lower internal hinges a a remain without engagement with their loops. Therefore the two lower sashes c 0 can be pushed outwardly and will turn around the pivots of the external hinges b b and 6 5 Then the upper sash i may be lowered by means of the cord 76 and allowed to rest on the supporting ledge 71,. In this po sition the sash i may serve as a guard to protect children or other people from leaning too much out of the window. Also the sashi will secure the two outwardly turned sashes c 0 against motion under the action of a wind or the like. The two locks Z Z having engaged beneath the two shells b will prevent the two sashes from moving upward and thereby prevent the pivots of all the external hinges I) b and b b from getting off their loops. at y are rabbeted ledges which are connected with the under side of the upper sashes and with the upper side of the supporting ledge respectively and which prevent the lower sashes, when the latter are partly lowered, from moving outward, and when they are wholly lowered, from moving inward. For again closing the window, it is only necessary to raise the upper sash i, to turn inwardly the two lower sashes c c and to turn the hand crank g in the opposite direction for raising the supporting ledge h. The loops of the two lower internal hinges a a should always be turned aside when not in use. When it is desired to clean the window quite comfortably and with perfect safety, the loops of the two lowerinternal hinges a a are turned to bring them in alinement with the pivots .of said hinges and the hand crank g is turned to lower the supporting ledge h. Then the pivots of the two lower internal hinges will engage in their loops, while those of the two upper internal hinges still remain in engagement with their loops, but the pivots of all the external hinges b b and b b are out of engagement with their loops. Therefore the two lower sashes c 0 can be drawn inwardly and will turn around the pivots of the internal hinges a a and a a In this position they can becleaned. Also the upper sash i can be lowered and equally cleaned easily and safely.
